   1 NVIDIA Tegra20 real-time clock
   2
   3 The Tegra RTC maintains seconds and milliseconds counters, and five alarm
   4 registers. The alarms and other interrupts may wake the system from low-power
   5 state.

   7 Required properties:
   8
   9 - compatible : For Tegra20, must contain "nvidia,tegra20-rtc".  Otherwise,
  10   must contain '"nvidia,<chip>-rtc", "nvidia,tegra20-rtc"', where <chip>
  11   can be tegra30, tegra114, tegra124, or tegra132.
  12 - reg : Specifies base physical address and size of the registers.
  13 - interrupts : A single interrupt specifier.
  14 - clocks : Must contain one entry, for the module clock.
  15   See ../clocks/clock-bindings.txt for details.

  17 Example:
  18
  19 timer {
  20         compatible = "nvidia,tegra20-rtc";
  21         reg = <0x7000e000 0x100>;
  22         interrupts = <0 2 0x04>;
  23         clocks = <&tegra_car 4>;
  24 };
